Application led October 19, 1926. Serial No. 142,575.

It is the object and effect of my invention to provide a radiator of cellular structure, including thin sheet metal walls, preferably copper, forming Iseparate passageways for a heat carrying Huid and a heat absorption fluid and means for forcing circulation of fluid through said cellular structure.

As hereinafter described, my invention includes a cellular structure comprising an annular congeries of metal tubes having enlarged polygonal ends which fit together; casing bands at the inner and outer edges of said congeries; means sealing the joints between the ends of vsaid tubes and said casing means.v forming a cellular honeycomb o f thin metal walls comprising separate passageways for hot water or steam, and for atmospheric air; means forming an inlet port and an outlet. port in communication with the passageways for the heating medium; an electric motor, mounted in the axial openingr in said annular congeries; and

a fan connected with said motor, adjacent.

to one end of lsaid tubes, arranged to circulate air through the'air passageways of said congeries;

In such a structure; there is a tendency for the fan to transmit vibrations to the cellular structure and generate sound which it is desirable to suppress. Therefore, adjunctive features of my invention are means for suspending or otherwise supporting said structure in spaced relation with a wall including meansfor limiting ,the transmission of such Vibration. As hereinafter described, Such su porting means includes a wall bracket aving means to rigidly connect it with a wall and having means to flexibly engage the pipes leading to and from said cellular structure and also the electric con.- ductors leading tothe fan motor.

My inventionincludes the various novel features lof construction and arrangement hereinafter more definitely specified.

In said drawings; Fig. I is an outer face view of a radiator and its appurtenances embodying my invention; the fan being omitted.

Fig. II is a diametrical sectional View of i of the tubes are in` spaced relation lto afford passageways 5 around and between them for the heating medium. Each of said tubes forms a passageway 7, extendingaxially through it, for .atmospheric air, such air passageways, of course,being\separated by the wall of said tubes, from the passageway/s around the tubes which contain the heating medium. 1

I find it conveni nt to provide said cellularV structure with casing means including band sections 9 of sheet metal at the outer circumferential edge of the structure, and a parts into molten half and half solder or other suitable metal capable of uniting them, as indicated at 15 in Fig. I.

The electric motor 16 is mounted in the axial opening 17 in said annular congeries; preferably with a bushing 18 of resilient rubber or other vibration suppressing material interposed between the cellular structure and the motor to suppress or limit the transmission of vibrations between them. The armature shaft 2() of said motor is provided with the fan wheel 21 adjoining one end of the congeries of tubes, and I prefer to providesaid fan with a guard 23, conveniently formed of a cage of wires having ends 24 bent to fit in and frictionally engage certain of the tubes 2; as indicated in Fig. I. In order to suppress or limit the transmission of vibrations from the motor vto said guard and rattling of the latter; I coverV the wire ends 24 with small rubber tubes 26 which frictionally, but detachably, engage said tubes 2.

In order to permitfree circulation of the atmospheric air with respect to said radiator; I prefer to support the latter in spaced relation with the Wall 27; which may be a ceiling or a side wall. Suchsupporting means may include the bracket 28, convenientlyy formed of pressed sheet metal, having means for rigidly connecting it with ing .33 having the antivibration bushing 34 arranged to embrace the electric conductors 36 and 37 through which said fan motor is energized. As indicated .in Fig. II; said ipes 13 and 14 are preferably provided with eat insulating coverings 39, which may be of any suitable character; and said pipes 13 and 14 and said electric conductors 36 and 37 may be gathered together to extend through a single conduit in said wall.

I do not desire to limit myself to t-he precise details of construction and arrange-l ment herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the ap nded claims.
